A recent study found that football players' brains do not fully recover from head hits, even after six months of rest. The study suggests that inflammation may be a key factor in whether players recovered within six months.
A study found that catch-and-release angling creates a window of opportunity for brood predators to consume young largemouth bass. After being caught and released, the male takes an average of 30 minutes to return to its nest, allowing predators to quickly exploit the vulnerability.
A study on roe deer in France's Champagne region found that the species has failed to adapt to earlier spring arrival, leading to reduced survival rates of fawns and a downward trend in population growth. Climate change is threatening the survival of this commercially important long-lived mammal.
A large-scale study found that cholesterol levels tend to be worse in the colder months compared to warmer months, with significant variations in lipid profiles. The researchers speculate that behaviors such as reduced sun exposure and lower vitamin D levels during winter may contribute to these seasonal fluctuations.
A 39-year study reveals that more than two-thirds of alpine flowers have changed their blooming patterns in response to climate change.
